TO ALL WHOM IT MAY CONCERN:

Be it known that I, T. F. ALLYN, of Nyaek, in the county of Roekland,and State of New York, have invented a new and improved Buffer orGar-Spring; and I do hereby declare that the following is a full andexact description thereof, reference being bad to the accompanyingdrawings, making a part of this specification.

Figure 1 is a vertical section of my spring.

.Figure 2 is a perspective view of the same.

The nature of my invention consists'in compressing wool or woollenbobbin into the aperture or hole which may be made in a rubber spring,thereby forming a combination which increases, to a great extent, theresisting and sustaining power of the spring.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation. I

I compress wool or woollen bobbin into the hole which is made in thespring, and with this combination I produce a spring atless expense andmore durable than the rubber spring without the aid of wool or bobbin.

It'will be seen that the two materials, or any similar or known materialcombined with rubber in the manner before stated, will act together, andthat .the woollen bobbin will'resist a greater pressure than rubberwithout being fractured or injured, as is frequently the case with therubber springs alone. I apply my spring in the same manner whichordinary rubber springs are applied.

What I claim as my invention, and desire to. secure by Letters Patent,is-

r A car-spring constructed of wool and rubber, combined as described andset forth in my specification.
